The invention relates to a device cree arating portions of equal-lengths''- "from a fleece roll, for the purpose of'ex'a ing theiruniformity. 1

A broad band of fibrous material, for mstance such as the fleecedelivered by a beat- 7 ing machine, has been controlled or examined upto now by continuously pulhng down from the roll, by hand, equallengths, 1 by using a measure pattern, in order to proceed subsequentlyto weighing the material. In this way, the uniformity of the roll Wlllbe controlled over the complete length of material. This art ofcontrolling is compliu cated and time-wasting and furthermore,

does not always secure perfect results, owing to the manually operatedpulling down. It has, however, also been proposed to perform theseparation of determined lengths go of fleece in a mechanical manner,and namely by means of a foot-operated comb, which operates a breakin ofthe fleece held between a second comb. ndependently of the fact thatsuch device is used for separating and g3 folding determined lengths offleece in the manufacture of wadding, it is not possible to obtain bmeans of said device a clean separation iiy the dropping comb, andfurthermore, the pulling off of determined lengths of the fleece rollhas to be effected by hand.

These drawbacks are eliminated by the device in conformity with theinvention, by the fact that the fleece is passed through a rollingdevice, 5 drawing in the example, in; the. accompanying drawing, in

Upon

the shaft of the separating roller 7 is mounted a pinion 14, meshingwith a 15, so that this latter,

toothed wheel which is mounted on a shaft 16, will continuously rotatewhen the 7 driving means 9, 1O jacent to the toothed are clutched in.Adwheel 15 is arranged, on the shaft 16, an interrupted toothed wheel17,

the interruption in. the teeth being referred to I in the drawing by 18.This interrupted n toothed wheel 17 is meshing with a pinion 19,

which constitutes a driving wheel both for the shaft 20 of this pinion19 roller 12 and for the drawing roller 5. For this purpose, themovement of is transmitted in anyijconvenient manner to the pullingroller 12,

for instance by means of the pinion 19 meshing with the'correspondingpinion 21 of the pulling roller 12.

The drawing in roller 5, through its pinion. 9 I 6, is driven by meansof an intermediate pinion 22 meshing with a pinion 23 mounted on theshaft 20.

It is obvious that instead of the crank 9 with pinion 10, any

Moreover, under ,lcertain roller gcooperating with the ta othermechanical driving conditions, a

c'lampvortongs can be' inserted between the .pairsof separatingfrollersand the pulling ble, said tongs 10o ice being provided for holding thefleece at the moment when the pulling device is stopped.

It can easily be seen that, when the driving of the machine is started,the fleece a will immediately be delivered from the roll by the drawingroller 5, and that it will progress under the action of the pullingroller 12, between the latter and the table 13, and afterwards engageand progress between the separating rollers 7 and 8.

This progression is continued until the interruption 18 of theinterrupted toothed wheel 17 will reach the pinion 19, the drawingroller 5 as well as the pulling roller 12 being stopped at this moment,whereas the pair of separating rollers 7, 8 will rotate further on. Forthis reason, the fleece will be detached along a sharp separating lineat the spot A and the separated part will fall down.

For the purpose of appreciating the disentangling capacity of the fibreflocks worked in the beating machine, and the purity of the fleecewithin the separate pieces, while controlling the uniformity of same byweighing, a slope 24 of translucent material has been provided, forinstance in an unpolished glass plate which is illuminated by diffusedlight from the rear. 25 designates corresponding lamps and 26 thereflecting screen provided in the machine.

In a particular form of embodiment, a locking disc 27 with kerf 28 hasbeen mounted on the shaft of the pinion 19 which is driving the pullingroller 12 (Fig. 3), and a peripheral band 29 has been provided on one ofthe toothed wheels 15 or 17; in the embodiment illustrated, said band isprovided on the toothed wheel 17. The kerf 28 is arranged in such aposition that the peripheral band will directly engage said kerf, whenthe teeth of the interrupted toothed wheel 17 will release the teeth ofthe pinion 19. In this manner, the pulling roller 12 is held in itsposition until the teeth of the interrupted toothed wheel 17 will againmesh with the pinion 19.

Instead of one kerf, it is possible to pro-' vide a plurality of kerfs,according to the transmission ratio of the wheel 17 and the pinion 19.
